Porting on i.MX6

I'm trying to port genode onto i.MX6. I cloned your work to see if it works
on my MX6Q-sabrelite. I followed the following steps:
1. ./tool/create_builddir hw_imx6 BUILD_DIR=imx6
2. In imx6, I did a RUN_OPT="--target uboot" make run/printf
3. I transferred the uImage using tftpboot at 0x20000000
4. bootm 0x20000000
It reaches the "starting kernel" stage and gets stuck there.
I did a readelf to see if the address I chose overlaps the bootloader. It
doesn't seem to.
Entry point 0x10005d70
Type Offset VirtAddr PhysAddr FileSiz MemSiz Align
EXIDX 0x07dd3c 0x1007dd3c 0x1007dd3c 0x018a8 0x018a8 0x4
LOAD 0x001000 0x10001000 0x10001000 0x47fc0 0x47fc0
LOAD 0x049000 0x10049000 0x10049000 0x39768 0x262c55
Any pointers on where I'm going wrong?
